Final Jeopardy

What is the density of oceanic crust?

About 3.0 g/cm3

What is the depth, below the surface, of the outer core?

2800 - 2900 km

What is the interior temperature at a depth of

3000 km in the earth?

5000oC

What is the melting point of the rock at a depth of 4000 km?

About 5500oC

The Cascades

What is the name of the mountain range that lies on the western edge of the North American

continent?

The 'plastic mantle' is also known as the..........

Asthenosphere

What is the pressure at a depth of 3500 km below the surface of the earth?

(GIVE UNITS!)

About 2 million atmospheres

In what state of matter is the rock at a depth of 3500 km in

the earth?

Liquid

DAILY DAILY DOUBLEDOUBLE

You may wager some or all of your money.

What is the thickness of the outer core?

2200 - 2300 km

What is the name of the interface between the crust and

the plastic mantle?

The MOHO

How long does it take S waves to travel 3000 km?

10 minutes

How far will P waves travel in 11 minutes 20 seconds?

8000 km

A seismic station is 4000 km from the epicenter of an earthquake. How long after P waves arrive will the S waves arrive at the

same station?

5 minutes 40 seconds

It takes P waves 11 minutes and 20 seconds to travel from the epicenter of an earthquake to a seismic station. How long

will it take S waves from the same earthquake to reach that seismic station?

20 minutes and 40 seconds

S waves from an earthquake arrive at a seismic station at 2:15:20 PM. If the

seismic station is located 2000 km from the epicenter, at what time did the

earthquake occur?

2:08:00 PM

What is the difference in arrival time between P and S

waves at a distance of 2600 km from an epicenter?

4 minutes

As the distance from an epicenter increases, the

difference in arrival time between P & S waves ...........

Increases

An earthquake occurs at 3:30:00 AM. At what time will S waves arrive at a seismic

station located 6500 km from the epicenter of the quake?

3:48:00 AM

The difference in arrival times between P and S waves is 5 minutes and 20 seconds. How far from the

epicenter is the seismic station located?

3600 km

The difference in arrival times between P & S waves is 7 minutes

and 20 seconds. If the P waves arrived at the station at 6:45:00 PM,

at what time did the earthquake occur?

6:36:00 PM

What term is used to

describe the area in the diagram

where "No waves" are recorded?

Shadow Zone

The location inside the earth where the earthquake actually

occurs is called the........

Focus

Why does zone 3 in the diagram

receive P waves

but no S waves?

S waves cannot travel through the liquid outer core

Which letter in the

diagram represents

the epicenter

of the quake?

Location C

What kind of plate boundary is depicted in the diagram?

A transform boundary
